There is a patch for DDR 5 on mega games. It was only added a couple of days ago so maybe you missed it.

It probably wouldn't hurt you to go ahead and burn yourself a copy of Import Player. You can also find this on megagames. It has a function on it that kills the mod detection. You just burn it and then boot it up setting the mod detection killer on and then swap your disc. It has worked on all the games that I have tried with a mod killer.

hey first time posting but newer games have the same road sign that king nero mentioned. I generally copy games so i have a back up because my son had "accidently" destroyed over $200 worth of games. I recently picked up spyro year of dragon and it wont play at all in my playstation console therefore neither does a copy, i get that road sign all the time.
if anyone has any suggestions on this it'll be greatly appreciated as no returns are allowed on these things. thx
